Good things first: the attention given over the phone before going, the attention by the same lady in the reception on the day of arrival, both very good and friendly.
Then the bad things: The room was visibly dirty, the showerhead had fallen off - they promised to repair it but never did!! We paid for the breakfast upon arrival to find next morning that it hadn't been written down (I still had the invoice though)
Finally the most horrible: We brought our dog, verified before going that we could bring him and it was no problem at all. When we arrived we left him well fed, walked and watered in our room as we had to attend a wedding (inside the flat with the door locked) only to find upon our return that our dog was alone, outside of our room... Apparently he had been barking and annoyed the rest of the guests but nobody had bothered to call us... Very poor service if you're supposed to be used to dealing with dogs and people living close...
